Cylinder liners and piston rings conditions are vital for continuous running of an engine. There are few studies about how the environment can affect cylinder liners and piston rings of metallic wear in 2-stroke slow speed engine. The paper aim is to include environmental effect on model of condition based monitoring (CBM). By considering environment impact on metal wears rate that is generated from cylinder liner. We monitored iron particle and residual Base Number (BN) of drain cylinder oil from 2-stroke slow speed engine that sail in different atmosphere. All ships monitored start sailing from Japan ports to US ports and another set of ships from Japan ports to Australia and New Zealand ports. Condition based monitoring on cylinder liners current in-use do not put the prospect of sailing environment as factors that can affect diesel engines. From analyzed drain oil results showed that ships sailing to Australia and New Zealand ports generate more of metallic element than ships sailing to US.
